WOOL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 293,789, dated February 19, 1884.

Application filed March 2, 1883. (No model.)

in the county of Middlesex and State of Mas-- sachusetts, have invented a new and useful Improvement in Wool-Washing Machines, of which the following is a specification.

Our invention relates to wool-washing ina-l chines; and it consistsin arranging two sets of toothed bars, which alternately reciprocate and carry the wool forward through the bowl of the washing-machine, at an incline upward, through the length of the machine, so as to carry the wool from within the liquid of the machine, and where it is fed in upward and forward, and for a considerable distance above the liquid before it reaches the squeeze-rolls, these sets of toothed bars being the only means of so conveying the wool out of the bowl 4and through the 'space above the liquid to drain it; secondly, in providing above these toothed bars sprinklingpipes, extending transversely across the bowl where the wool is being carried above the surface of the liquid, which has the effect of rinsing and cleansing the wool with fresh liquid while passing through the air to the squeeze-rolls; thirdly, in providing a feeding-roller for feeding the wool into the bowl, which do's the wool from it and prevents its adhesion to its surface by means of liquid forced through perforations in its shell and, fourthly, in providing a doffer-roller for the lower squeeze-roll which doffs the wool from the surface of that roll, and has the wool thrown off from its surface by means of perforations in its shell, through which liquid is forced for that purpose.

Heretofore two sets of reciprocating bars have been used to convey wool through the bowl of the woolwashing machine to the squeeze-rolls', said bars being provided with teeth and reciprocating alternately, but such bars were not placed at an incline extending from the bottom of the bowl at its feed-in end to the top of the chute at the squeeze-roll end, and so as to' convey the wool for a considerable distance through the air above the liquid before reaching the squeeze-rolls. We place these bars in this position, and to increase the efficiency of the bowl we provide sprinklers for saturating the wool with fresh washingliquid where it passes through the air, thus enabling the wool to be passed under the washing process of two or more qualities of washing-liquid in the same bowl.

Heretofore it has been necessary to pass the wool through successive bowls of the machine to accomplish this, the heavier and greasier liquid being in the first bowl, another quality of liquid in the second bowl, and so on; but by our invention we reduce the number of bowls necessary to be used in the practical operation of the machine. Ve also provide a feeding-roll for conducting the wool into the machine, and a doft'er-roll for conducting it away from the squeeze-rolls into the next bowl so constructed as to have perforations in their shells, through which liquid is forced from a pump while they are in revolution, and the wool thrown from their surfaces as well as forcibly saturated with the washingliquid,

which is thus caused to penetrate more thoru oughly through the iibers and open up and cleanse them better.

In the drawings, Figure l is a top plan view of the machine, with a part of the reciprocating bars and perforated bottom underneath broken away to show the construction of parts. Fig. 2 is a longitudinal vertical section through the machine, showing the operation of the several parts.

A is the bowl of the machine, constructed in the usual manner.

B B are the squeeze-rolls, arranged so as to be almost entirely above the surface of the liquid in the bowl.

H is a force-pump attached to the side of the machine, and driven by a shaft, h, and pulley h. This pump is used not only to draw away the contents of the bowl in cleansing it through the perforated pipes a', extending across the bottom of the bowl, Abut also, when the washing of the wool is going on, to force liquid through other pipes, for assisting in the operation, substantially as hereinafter described. l q- In the bowl of theV machine, and inclining upward from the end where the wool is -fed in, is placed a perforated removable bottom or incline, D, provided with perforations (1, for

the escape ofthe liquid through it, and a larger perforation, d2, to operate the reciprocating toothed bars through. This inclined bottom D serves to prevent the iiber from being washed down between the bars by the force of the washing-liquid from t-he pipes c a above falling upon them, as hereinaiter described.

c ci are two sets of toothed bars, running longitudinally the whole length of the bottom D, all the bars covering it for the entire breadth of the machine. These bars c c have cracks or joints between them sufficient to allow the washing -liquid to escape down through them and the perforated bottom D underneath. All the bars c are attached together, and all the bars cL are attached together, and one set, c, is made to reciprocate in one direction by the pitman c, while the set e2 is made to reciprocate in the opposite direction by the pitman c, the pitmen c" and c4 being driven bythe oppositely-placed eccentrics on the shaft G, which is in turn driven by the pulley g.

c is a feed-roll for feeding or conveying the wool into the machine, and is composed of a perforated shell, as shown, mounted upon a shaft, C, driven by pulley c`. The shaft C is hollow and perforated, and leads through bearings into the pipe cI in such a manner that liquid forced through this pipe will pass through the shaft and its pcrforations, and out through the shell of the roll r, and striking with force wool from the feed-roll c upon the reciprocating bars c c2.

N is a doit'er-roller, constructed in all reA spects similar to the roller c, and, combined with its shaft `n and pipe n?, leading to the pump H in substantially the same manner. It serves to deff the wool from the lower squeeze-roll, B, and to saturate it with a cleansing-liquid, which finally ri nses it as it passes from the machine. It revolves in the same direction as the lower squeeze-roll, and is driven by a cord leading around its shaft or' axis, as indicated in dotted lines in Fig. 2.

a c are pipes leading across the bowl over the part of the reciprocating bars c c2 which is above the surface of the liquid in the bowl A. These pipes are perforated on their lower sides, and are connected by the pipe al with the force-pump. Liquid forced through them falls upon the wool above the liquid in the bowl, and serves to wash and rinse the latter thoroughly before reaching the squeeze-rolls. The pipes a are connected to the pump by the pipe a, and a valve, c, is provided to shut them oi and open the pipe a when desired.

By iirst washing the wool in the greasier and dirtier liquid in the bowl A, and then forcing through it a clean, liquid from the pipes a and doffer-roll N, after it has left the liquid in the bowl A, we are enabled to greatly increase the capacity of the bowl. In explanation of this it should be stated that it is customary to use a greasier, dirtier, and heavier liquid for-washing in the irst bowl, a different one in the second, not .so greasy or dirty, and still different ones in the third and fourth bowls; and when the liquid in the iirst bowl becomes too much impregnated with grease and dirt it is drawn oil' and replaced by the liquid of the second bowl, and the second by that of the third, and so on, fresh liquid being placed in the last bowl of the machine, through which the wool passes. By this means the washing-liquid is utilized toits full capacity, and the wool, when iinally coming from the machine, passes last through the clean washing-liquid.

By using a cleaner washing-liquid for forc- 'ing through the pipes a a and doffer-roll N,

we are e'nabled to subject the wool to the effeet of two liquids in one bowl, and by allowing cleaner liquid to drain from the wool into the bowl we can draw off the dirtier and heavier parts of the liquid, by theuse ofthepump, through the pipes c a', and we are thus enabled to keep the liquid in the bowl A more nearly of au even quality,while increasing the washing capacity of the bowl.

\Vhat we claim as new and of our invention isi l. In combination with the bowl A, the perforated feed-roll c, connected with the pipe c, and arranged on the bowl, substantially as described. Y

2. The perforated dotfer-roll N, connected with the pipe a2, in combination with the squeeze-rolls B B, substantially as described.

3. In combination wit'hthebowlA, squeezerolls B B', and bottom l), the alternately-reciprocating sets of bars c ci, extending from the bottom of the bowl at the feed-in end entirely below the surface of the liquid to said said squeeze-rolls above the surface ofthe liquid at the delivery end, and upon an incline partly below and partly above the surface ofthe liquid in the bowl, and adapted to convey the fiber from the feed-in end to the delivery end ot' the bowl upon said bars, substantially as described.

Ll. In combination with the bowl A, the bars e et, extending partly below and partly aboveI the surface ofthe liquid in the bowl, and adapted to convey the fiber thereon through the same, one or more perforated pipes, c, extending over the portion of the carrier above the liquid in the bowl, substantially as described.
